Title: Seismoscope
Inventor: TSUGII HIDESHI
IPC: G01H1/00
Filed: 1988-12-30
Abstract: PURPOSE:To obtain a seismoscope of easy, small-sized constitution which displays an automatic leveling function and has stable operation characteristics even when roughly fitted by suspending and supporting a case by a fitting frame so that the case rotates and swings within a specific angle range so as to hold the horizontal attitude. CONSTITUTION:When the fitting frame body 12 is fitted to an instrument slantingly at less than a specific angle to the horizontal surface H, the case 1 rotates and swings on the fitting body 12 around the hemispherical surface part at the lower end of a suspension shaft 18 to maintain the horizontal attitude, so a steel sphere 3 neither moves nor abuts on the cylindrical plunger part 4A of a plunger 4, so the operation characteristics of the seismoscope are not affected. At such a time, an excessive swing between the fitting frame body 12 and case 1 is precluded by the damper function of an elastic body 19 which is a solid body. If vibration which exceeds a constant value is applied in this fitting state, the steel sphere 3 rolls and moves on the spherical body receiving surface 2 to collide against the cylindrical plunger part 4A of the plunger 4 and swing an actuator 5 into vibration sensing operation.
